There are many aspects of being an exercise physiology major. The field of exercise physiology has always interested me, but I was never sure about what career path I would choose. This year has really given me a better understanding of what path I would like to pursue. I really wanted to be an occupational therapist, but shortly after decided that I wanted to be a physical therapist. According to Writing, the annual salary for a physical therapist is in a range from $70,000-$100,000 (2010). I wanted a career that would keep me stable financially and this had that benefit. I also thought since I enjoy interacting with the public and seemed to have an interest in the rehabilitation process that this would be a perfect fit for me. However, this year I finally discovered that I did not want to do either of these careers. I want to attend graduate school and obtain a masters degree in exercise physiology or kinesiology. I came to this conclusion after taking advice from my professors. I realized that this career path offered many benefits like summers, weekends, and holidays off from school. After I obtain a masters degree in either exercise physiology or kinesiology, I would like to obtain my doctorate degree. I would like to obtain this degree to expand my knowledge of these fields and an increase in salary is always an advantage. I really admire the professors I have here at the university and they have inspired me to choose this career path. My main goal is to teach at a university and help students decide what it is that they want to do when they graduate with that exercise physiology degree. I have done research and most master’s degree programs for exercise physiology and kinesiology are two years. Besides the career path that I chose for the field of exercise physiology, there are many professional organizations that are very important to the field. The first organization is the ASEP (American Society of Exercise Physiologists). The ASEP is a professional...

...Cardio Pulmonary Practical
The main aim of the practical was to assess, what affects did light exercise have on the systolic and diastolic blood pressure, heart and respiration rate, tidal volume, minute volume and percentage of gas. The readings were taken before exercise, during exercise and after exercise. Blood pressure is defined as the amount of pressure exerted on the vessels walls, during blood flow. Blood pressure can be measured using a sphygmomanometer. The upper value indicates the systolic pressure; this is the highest level of pressure obtained. This is usually 120mm Hg in healthy adult. The diastolic blood pressure is the pressure achieved before the aortic valves reopen, which is usually between 70- 80mm (Barbara, J.C. 2005). The heart rate is the number of beats that is pumped by the heart per minute. It’s measured by taking the pulse rate. Respiratory rate is the number of breath exhaled and inhaled in a single breath. Respiratory rate can be measured simply by observing the person’s chest and stomach rise and fall. It is usually measured in breath per minute. Tidal volume is the amount of air inhaled or exhaled in a single breath. In an average human, the tidal volume is about 0.5litres, while the lungs can hold up to ten times more than this. Minute volume, is the amount of air or fluid moved per minute.
When working with human subject, many considerations need to be taken, firstly the age of...

...The Physiology of Fitness – Acute and long term effects on the body
Musculoskeletal System Response to acute exercise
Increased Blood Supply
During exercise your blood supply increases to your muscles, the reason for this is to keep them working and making sure that they don’t get tired too easily.
Increase in Muscle Pliability
During exercise your muscles will also become more pliable because as the muscles contract quickly they will generate heat, this then makes the muscles more pliable, reducing the risk of injury.
Increased Range of Movement
The body’s range of movement during exercise increases because you’re using your muscles to stretch out and allow your joints to move further therefore your range of movement is longer.
Muscle Fibre Micro Tears
During exercise the muscles are put under stress, so much so that it causes little tears to appear in the muscles fibres. The tears cause swelling in the muscle tissue, this then causes pressure on the nerve endings and pain. If the body gets the sufficient rest it needs to repair these fibre tears, then the muscle will be stronger that it was before.
Energy Systems response to acute exercise
Energy systems response to acute exercise happens when the exercise is high in intensity, which is too much for the cardiovascular and respiratory system to deal with. The first response is to use...

Short term responses
One short term response when playing basketball is when your face starts to go red, this happens because the body gets too hot and it tries to cool the body down by bringing blood to the surface of the skin to let some heat out and the skin also produces sweat to let out heat, therefore the skin surface goes red. Another short term response to physical activity is that your breathing rate and heart rate increases, the reason this occurs is because the muscles are being made to work harder and as a result of that the muscles need more oxygen so therefore you need to breathe in more oxygen and breathe out more carbon dioxide to keep the muscles going. Another short term change that occurs due to exercise is that the muscles become more pliable, the result in the change is due to the muscles in the body contract so quickly they generate heat, so when they contract quickly, the friction between the muscles generates heat, which in turn makes the muscles more pliable. It's just like an elastic band, when you stretch an elastic band a lot of times, the friction of the band generates heat, and you'll find that you will be able to stretch it even further. An immediate change in the cardiovascular system as a result of playing basketball is that the blood pressure increases, this cardiovascular response happens because when exercising, your blood needs to work harder...

...cardiorespiratory system to
improve the transport of oxygen to the working muscles also can improve through regular
exercise (Mc Kenzie, 2011). The exchange of oxygen and carbon dioxide between the lungs and
blood is termed pulmonary diffusion and is a central limitation to oxygen delivery that affects
VO2 max. It is not so much a limiting factor as compared to highly-trained athletes because
the structure and function of the lungs do not change even with consistent exercise. This poses
a hindering factor when they train at sea level and altitude and may develop problems like
exercise-induced hypoxemia (Mc Kenzie, 2011).
b) Other factors that may have a limiting effect on VO2 max include exercise mode, individual's
training state, heredity, gender, body composition and age. Most likely factors that limit it are
exercise mode and training state as evidenced by (McArdle et al., 2006), a definite training specificity exists when trained athletes achieved accurate VO2 max levels compared to non-trained athletes. The treadmill was also evidenced to achieve VO2 max more easily than other exercise modes (McArdle et al., 2006). VO2 max must also be determined relative to the individual's training state at the point of time (McArdle et al., 2006).
4) There are a few possible causes of the elevated VO2 max during recovery from exercise. The...

Responses To Steady-State Exercise
Once an athlete has been performing continuous exercise for a period of around 20 minutes, their body reaches a steady-state. Continuous exercise includes all forms of exercise that have no stopping periods such as jogging, swimming or cycling. Examples of non-continuous exercise would be weight lifting, interval training and boxing.
Steady state is when the body is working at a steady state it means that lactic acid removal is occurring at the same pace as lactic acid production.
Various changes will have occurred in the body to allow this steady state to occur.
Cardiovascular
• Heart rate levels off
• Increased stroke volume
• Vasodilation of blood vessels leading to working muscles
• Blood pressure levels off
• Thermoregulation
Respiratory
• Tidal volume levels off
• Breathing rate levels off
• Oxygen is unloaded from haemoglobin much more readily
Neuromuscular
• Increased pliability of muscles
• Increased speed of neural transmissions
Energy
• Aerobic ATP production
In cardiovascular response to steady state heart rate peaks during the first few minutes of exercise and then levels off. While exercising there is an increase in venous return. This increased volume of blood has the effect of stretching the cardiac muscle to a...

...Response to Acute Exercise
Introduction:
As a health and fitness instructor I need to be able to apply my anatomical and physiological knowledge to practical activities and exercises. I have conducted practical assessments to explore how the body responds to physical activity and exercise. I have then written a report, including all the anatomical and physiological changes that occur within each of the bodily systems.
Acuteexercises are a lower intensity for a shorter period of time. For example it could be twenty minutes on the treadmill. Acute responses are immediate responses to exercise such as an increase in body temperature and heart rate.

Aerobic endurance Multi stage fitness test Level 9.8
Flexibility Sit and reach 32cm
Muscular endurance Sit ups 25

Musculoskeletal Response to Acute Exercise:
There is an increase in blood supply as it has to go to the parts of the body that are exercising the most. For example if an individual took part in a cross country run, the blood supply would increase because their legs would need more energy. This means that there would be more blood circulating in their legs than normal because they are being overworked. During acute exercise muscle pliability increases allowing a greater range of movement. Acute exercise causes muscle fibre tears....
